The trade-off between the reliability of a communication message and its latency is studied in [1]} for an industrial IoT application.
To study this trade-off, the impact of the age of information that is received by the plant(s) from the central controller is investigated. This is done by obtaining the value function of every possible code length through value iteration algorithm. To be able to run a value iteration algorithm, the interaction of the central controller with the whole system, including the plants, is modelled by a semi Markov decision process. Therein, the length of error correction codes is designed considering the current state of the system rather than considering just the CSI of the communication channel. In that sense, the error correction block of the agents are co-designed with their control policy block.
